BLACKSM ITHS FORGE.

SPECIFICATION forming part of Letters Patent No. 232,174, datedSeptember 14, I880.

Application filed Juno 3, 1880.

To all whom it may concern:

Be it known that I, MATHIAS W. G. BUPP, of Bonneauville, in the countyof Adams and State of Pennsylvania, have invented certain new and usefulImprovements in Blacksmiths Forges; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,suchas will enable others skilled in the art to which it pertains tomake and I0 use it, reference being had to the accompanying drawings,.which form part of this specification.

My invention relates to an improvement in blacksmit-hsforges; and itconsists in a movable head for reducing or increasing the space in whichthe fire is to be built, and a slide which moves back and forth underthe grate, for the purpose of letting on or shutting off the blast, themovable head and slide being connected together, so that when the onemoves both will move, as will be more fully described hereinafter.

The object of my invention is to provide a means'by which the size ofthe fire in a black- 2 5 smiths forge can be regulated to the size ofthe work that is to be done, and thus prevent the useless consumption offuel.

Figure 1 is a vertical section of a forge embodying my invention. Fig. 2is a plan View 0 of the same. Fig. 3 is a perspective of the head andslide.

A represents the fire-chamber, which may be of any size desired, andwhich is lined with fire-brick or any other suitable material. In thebottom of this'chamber is placed a grate, B, upon which the fire isbuilt, and which grate is nearly as long as the chamber itself. Movingback and forth in this fire-chamber is thehead O, which may be of anyconstruction desired, and which can be drawn out ward for the purpose ofincreasing the space in which the fire is to be built, or pushed inwardtoward the left to any desired distance, so as to decrease the space.This head fits snugly between the walls of the firechamber, and, restingupon the top of the grate, it stops the blast of air through thegratefrom all points except that portion of the grate which is notcovered by the head. When the head is moved inward, near the inner endof the chamber, there is room for but a small fire,

(No model.)

but when the. head is drawn outward the size of the fire is increasedproportionately.

Moving back'and forth through the frame, just below the grate, is theslide D, which 5 5 serves to assist in cutting 011' the blast of airfrom all parts of the grate except that which is not covered by thehead, and the inner end of this slide projects forward slightly inadvance of the inner end of the head, so as to form a tightjoint-whenthe head is moved inward toward the inner end of the fire-chamber A, asshown in solid lines in Fig. 1, for the purpose of cutting off allblast. This head and slide are connected together by the same lever F,so that when one is moved both will move, and in the same direction.

Under the grate is the air-chamber, which is connected with the bellows,and in the lower part of this chamber there is made an opening, G, towhich a tube or pipe is connected by means of a collar, which collarforms a sufficiently-tight joint to prevent any leakage of air. All ofthe cinders or ashes which may fall into the aircham her from the grateabove will be carried off through this tube, which is provided with asuitable valve. This valve is opened when it is desired to let the ashesand cinders out, but is closed while the bellows are in operation, so asto prevent the cs cape of air at this point.

The great trouble with blacksmiths forges now in use is, that there isno means of regulating the size of the fire, and hence the fire isconstantly consuming a great deal of material which is not absolutelyneeded. Very frequently but a very small fire would answer for all ofthe work that is to be done, and yet as the coal is piled around in theforge, the fire is constantly increasing in size, and thus consumes asmuch fuel as would be necessary to finish a large job of work.

The object of my invention is to enable the blacksmith to regulate thesize of his fire to the amount of work to be done, and thus save 5 thewaste of a great deal of fuel.

Having thus described my invention, I claim- 1. In a blacksmiths forge,the combination of a movable head which is placed in the tire IOOchamber and a slide which moves with the head, the head and slide beingsecured to the operating-rod in such a manner as to bear In testimonythat I claim the foregoing I against opposite sides of the grate,snbstanhave hereunto set my hand this 20th day of to tially as shown.May, 1880.

2. In a blacksmiths for e, the combination 4 5 of a fire-chamber, A,grate B, and air-eham- MATHIAS BUPP' her with the head 0, slide D, androd F, the Witnesses: slide being longer than the head, substantially J0s. I. LIVERS, as set forth. J. E. MILLER.
